Normally this rake tends to dig in far too deeply and it is dif ficultto control the penetration without considerable effort.

Means have been provided in the past in an attempt to control this depthbut these usually are designed specifically for one type of rake and arenot interchangeable between makes or types.

SUMMARY OF THE INVENTION The present invention provides attachments foreach side of a rake which are adjustable up and down the sides tocontrol the depth of penetration. They include a clamp member and shoesor wheels which engage the ground or surface being raked and theprincipal object and essence of the invention is to provide such anattachment which is readily attachable to any type or make of rakewhether it be a toothed rake or a blade type rake.

Another object of the invention is to provide a device of the characterherewithin described which enables a rake, particularly a rake used ongrass to be pushed and pulled back and forth readily and easily withoutthe rake digging in or jamming.

A yet further object of the invention is to provide a device of thecharacter herewithin described which enables a rake to be usedinterchangeably on garden soil or lawns and, when used on garden soil,enables the rake to be used to lightly rake a seed bed or deeply rakewith a harrowing action.

A yet further object of the invention is to provide a device of thecharacter herewithin described which is simple in construction,economical in manufacture, and otherwise well suited to the purpose forwhich it is designed.

with the considerations and inventive objects herein set forth in view,and such other or further purposes, advantages or novel features as maybecome apparent from consideration of this disclosure and specification,the present invention con sists of the inventive concept which iscomprised, embodied, embraced, or included in the method, process,construction, composition, arrangement or combination of parts, or newuse of any of the foregoing, herein exemplified in one or more specificembodiments of such concept, reference being had to the accompanyingFIGURES in which:

DRAWINGS FIG. I is an isometric view of a blade type rake with myattachments secured thereto.

FIG. 2 is an isometric view of one of the attachments per se.

FIG. 3 is an end view of the rake and attachment shown in FIG. I.

In the drawings like characters of reference indicate correspondingparts in the different figures.

DETAILED DESCRIPTION In FIG. I, a blade type rake 11 is shown whichconsists of an arcuately curved blade 16 having teeth 17 formed upon thelower edge thereof and a socket 18 secured centrally adjacent the upperedge which receives the conventional rake handle 19 in the usual way.

The attachment 10 consists of a clamp member 13 which comprises avertically situated length of channel 20 engageable with the side edge21 of the rake II by the open side 22 of the channel as clearlyillustrated in FIG. 1. Means to detachably secure the channel take theform of the clamp bolt 12 having wings 23 secured to one end thereof,the screwthreaded bolt portion of clamp bolt I2 screw-threadablyengaging an aperture in one side flange 24 of the channel and thusholding the channel firmly in position upon the end of the rake.

An arcuately curved shoe 14 is secured adjacent one end 15 thereof tothe lower end of the channel and adjacent the closed side thereof sothat the shoe extends beyond the channel as clearly shown in thedrawings. The other end 27 of the shoe curves upwardly from the lowerend 25 of the channel and forwardly of the rake when attached as shownin FIG. I. It is of course appreciated that the attachment IOA securedto the other end or edge 21A of the rake is similar in construction butis handed with respect to the attachment 10.

In operation, the attachments are secured to the ends or edges 21 and21A of the rake and are adjusted so that the teeth 17 extend below theshoes 14 and by adjusting the attachments upon the edges, the depth ofpenetration is controlled.

FIG. 3 shows the rake in the normal working position with the shoe l4engaging the surface 31, it being understood that the inclination of theblade 16 causes the arcuately curved shoe to engage the groundintermediate the ends of the shoe as clearly illustrated in FIG. 3.

Various modifications can be made within the scope of the inventiveconcept which is herein disclosed and/or claimed. Accordingly, it isintended that what is set forth should be regarded as illustrative ofsuch concept and not for the purpose of limiting protection to anyparticular embodiment thereof, and that only such limitations should beplaced upon the scope of protection to which the inventor hereof isentitled as justice dictates.

What I claim as my invention is:

l. The combination of a rake including a transversely elongated rakingmember with downwardly projecting teeth, and a pair of ground-engagingattachments removably and adjustably mounted on the end edge portions ofsaid raking member to limit penetration of said teeth into the ground,said attachments being similar in construction and each comprising anelongated and longitudinally curved ground-engaging shoe, an upstandingplate provided at one side edge of one end portion of said shoe, a pairof spaced flanges provided at opposite side edges of the upper endportion of said upstanding plate and coacting with said upper endportion to define an open-sided channel which is open on that side ofthe plate opposite from said shoe, said channel receiving therein an endedge portion of said raking member so that said teeth project below saidshoe in a plane intermediate the ends of the shoe, and a clamping boltextending into said channel through one of said flanges for removablyand adjustably clamping the attachment on the raking member.
